Voters in the city of SeaTac have approved a $15 minimum wage, but opponents have already requested a recount.

Proposition 1 passed by a slim margin of 77 votes out of 6,003 votes cast. But even before the ballots were certified Tuesday, the group Common Sense SeaTac called for a recount in the hotly-contested initiative. The group is supported by Alaska Airlines, rental car companies and airport baggage-handling businesses.
